<h4 class="subsubsection">6.3.8.3 The Front End <samp>Make-lang.in</samp> File</h4>

<p>Each language subdirectory contains a <samp>Make-lang.in</samp> file.  It contains
targets <code><var>lang</var>.<var>hook</var></code> (where <code><var>lang</var></code> is the
setting of <code>language</code> in <samp>config-lang.in</samp>) for the following
values of <code><var>hook</var></code>, and any other Makefile rules required to
build those targets (which may if necessary use other Makefiles
specified in <code>outputs</code> in <samp>config-lang.in</samp>, although this is
deprecated).  It also adds any testsuite targets that can use the
standard rule in <samp>gcc/Makefile.in</samp> to the variable
<code>lang_checks</code>.
</p>
<dl compact="compact">
<dt><code>all.cross</code></dt>
<dt><code>start.encap</code></dt>
<dt><code>rest.encap</code></dt>
<dd><p>FIXME: exactly what goes in each of these targets?
</p></dd>
<dt><code>tags</code></dt>
<dd><p>Build an <code>etags</code> <samp>TAGS</samp> file in the language subdirectory
in the source tree.
</p></dd>
<dt><code>info</code></dt>
<dd><p>Build info documentation for the front end, in the build directory.
This target is only called by &lsquo;<samp>make bootstrap</samp>&rsquo; if a suitable
version of <code>makeinfo</code> is available, so does not need to check
for this, and should fail if an error occurs.
</p></dd>
<dt><code>dvi</code></dt>
<dd><p>Build DVI documentation for the front end, in the build directory.
This should be done using <code>$(TEXI2DVI)</code>, with appropriate
<samp>-I</samp> arguments pointing to directories of included files.
</p></dd>
<dt><code>pdf</code></dt>
<dd><p>Build PDF documentation for the front end, in the build directory.
This should be done using <code>$(TEXI2PDF)</code>, with appropriate
<samp>-I</samp> arguments pointing to directories of included files.
</p></dd>
<dt><code>html</code></dt>
<dd><p>Build HTML documentation for the front end, in the build directory.
</p></dd>
<dt><code>man</code></dt>
<dd><p>Build generated man pages for the front end from Texinfo manuals
(see <a href="Man-Page-Generation.html#Man-Page-Generation">Man Page Generation</a>), in the build directory.  This target
is only called if the necessary tools are available, but should ignore
errors so as not to stop the build if errors occur; man pages are
optional and the tools involved may be installed in a broken way.
</p></dd>
<dt><code>install-common</code></dt>
<dd><p>Install everything that is part of the front end, apart from the
compiler executables listed in <code>compilers</code> in
<samp>config-lang.in</samp>.
</p></dd>
<dt><code>install-info</code></dt>
<dd><p>Install info documentation for the front end, if it is present in the
source directory.  This target should have dependencies on info files
that should be installed.
</p></dd>
<dt><code>install-man</code></dt>
<dd><p>Install man pages for the front end.  This target should ignore
errors.
</p></dd>
<dt><code>install-plugin</code></dt>
<dd><p>Install headers needed for plugins.
</p></dd>
<dt><code>srcextra</code></dt>
<dd><p>Copies its dependencies into the source directory.  This generally should
be used for generated files such as Bison output files which are not
version-controlled, but should be included in any release tarballs.  This
target will be executed during a bootstrap if
&lsquo;<samp>--enable-generated-files-in-srcdir</samp>&rsquo; was specified as a
<samp>configure</samp> option.
</p></dd>
<dt><code>srcinfo</code></dt>
<dt><code>srcman</code></dt>
<dd><p>Copies its dependencies into the source directory.  These targets will be
executed during a bootstrap if &lsquo;<samp>--enable-generated-files-in-srcdir</samp>&rsquo;
was specified as a <samp>configure</samp> option.
</p></dd>
<dt><code>uninstall</code></dt>
<dd><p>Uninstall files installed by installing the compiler.  This is
currently documented not to be supported, so the hook need not do
anything.
</p></dd>
<dt><code>mostlyclean</code></dt>
<dt><code>clean</code></dt>
<dt><code>distclean</code></dt>
<dt><code>maintainer-clean</code></dt>
<dd><p>The language parts of the standard GNU
&lsquo;<samp>*clean</samp>&rsquo; targets.  See <a href="http://www.gnu.org/prep/standards/html_node/Standard-Targets.html#Standard-Targets">Standard Targets for
Users</a> in <cite>GNU Coding Standards</cite>, for details of the standard
targets.  For GCC, <code>maintainer-clean</code> should delete
all generated files in the source directory that are not version-controlled,
but should not delete anything that is.
</p></dd>
</dl>

<p><samp>Make-lang.in</samp> must also define a variable <code><var>lang</var>_OBJS</code>
to a list of host object files that are used by that language.
